The magazine, originally conceived as a newsletter for users of the Ferguson Big Board (a single-board CP/M computer), was published bi-monthly beginning in July 1981. It soon expanded its coverage to other board-level computers, the Kaypro computer, and general hobbyist/experimental computing, with special interest areas being robotics, interfacing, embedded systems and programming languages. The magazine carried articles on a wide range of subjects, some system-specific and newsletter-like, but also covering (then) off-mainstream topics, e.g. 3D graphics, artificial intelligence, or the special needs of handicapped users. They published a 32-page catalog of CP/M and MS-DOS software, cover date Fall/Winter 1986, describing it as the second, the first having been the Spring issue.
"Micro C", as the magazine was known to its fiercely loyal readership, routinely published circuit diagrams and source code. The magazine was shut down after more than 50 issues in 1990, reportedly due to the editor's change of interests.
